UNDATED -- Will your kids be clamoring for an Elmo that gives hugs, a loom that lets you make rubber bracelets or a kid-size go-cart this holiday? Those and others have made Toys R Us' annual list of "hot" toys that the company is betting kids will want around holiday time. It's a crucial calculation because retailers can make up to 40 percent of annual holiday sales during the holiday season, so Wayne, N.J.-based Toys R Us needs to make sure it has the right mix of toys at the right prices. Overall holiday spending is expected to be cautious. Retail revenue in November and December is expected to rise 2.4 percent during the biggest shopping period of the year, Chicago-based research firm ShopperTrak said Tuesday.
